Title: Precure tread for retreaded tire and its manufacturing method
Inventor: SEKI YASUHIRO
IPC: B29D30/56
Filed: 2000-04-12
Abstract: PROBLEM TO BE SOLVED: To effectively suppress exfoliation of a precure tread 11 from a base tire. SOLUTION: A width direction inner end (an inclination starting point P) of an inclined plane 17 is separated from a tread end T by 5 mm or more and an external surface 15 at a tread end T side from the point P is indented gradually deeper so that when this retreaded tire falls down in an acting direction of lateral force, the end part external surface 15 at the tread end T side from the point P and a road surface become substantially parallel and the tread end part and the road surface contact at a wide area. By this, the lateral force acts not as a force peeling up the precure tread 11 but as shearing force on a boundary between the precure tread 11 and the base tire 12.
